Helo All, I have a similar problem on my environment, in my case I have a e-commerce application and if the container returns the EJBException (transaction is not active) my instance crash with java.lang.OutOfMemory on heap space. Anyone have the solution of this? It is a bug of jboss or is a error of the application? My env is: Jboss 4.0.3SP1 on Linux RedHat Enterprise 4. JVM 1.5.0_09 thanks for all.
